This class handles waiting for a response to a given request and the subsequent response association.
Initializes a response waiter instance for the supplied request identifier.
# File lib/rex/post/meterpreter/packet_response_waiter.rb, line 21 def initialize(rid, completion_routine = nil, completion_param = nil) self.rid = rid.dup self.response = nil if (completion_routine) self.completion_routine = completion_routine self.completion_param = completion_param else self.done = false end end
Notifies the waiter that the supplied response packet has arrived.
# File lib/rex/post/meterpreter/packet_response_waiter.rb, line 44 def notify(response) self.response = response if (self.completion_routine) self.completion_routine.call(response, self.completion_param) else self.done = true end end
Waits for a given time interval for the response packet to arrive. If the interval is -1 we can wait forever.
# File lib/rex/post/meterpreter/packet_response_waiter.rb, line 58 def wait(interval) if( interval and interval == -1 ) while(not self.done) ::IO.select(nil, nil, nil, 0.1) end else begin Timeout.timeout(interval) { while(not self.done) ::IO.select(nil, nil, nil, 0.1) end } rescue Timeout::Error self.response = nil end end return self.response end
